High Alumina Castable Introduction
High alumina refractory castable is an unshape material made by mixing high alumina bauxite as the main refractory aggregate, adding additives, binders, and other materials. Mixing with water can be directly used, using vibration casting for molding. Generally speaking, the operating temperature range is between 1400 ° C and 1600 ° C. High alumina castable can be directly cast into an integral lining on industrial furnaces or prefabricated into fire-resistant prefabricated blocks, which can be used for masonry in industrial furnaces.
Characteristic of High Alumina Castable
1.Has a certain degree of corrosion resistance;
2.High refractory temperature and high load softening temperature;
3.High compressive strength and excellent thermal shock resistance;
4.High density, low porosity.
5. Good resistance to flake performance.
